--aligned
Use with --separator to align the output columns
-a|--all
Show information about internal LVs. These are components
of normal LVs, such as mirrors, which are not independently
accessible, e.g. not mountable.
--binary
Use binary values "0" or "1" instead of descriptive literal
values for columns that have exactly two valid values to
report (not counting the "unknown" value which denotes that
the value could not be determined).
--commandprofile String
The command profile to use for command configuration. See
lvm.conf(5) for more information about profiles.
--config String
Config settings for the command. These override lvm.conf(5)
settings. The String arg uses the same format as
lvm.conf(5), or may use section/field syntax. See
lvm.conf(5) for more information about config.
--configreport log|vg|lv|pv|pvseg|seg
See lvmreport(7).
-d|--debug ...
Set debug level. Repeat from 1 to 6 times to increase the
detail of messages sent to the log file and/or syslog (if
configured).
--devices PV
Devices that the command can use. This option can be re‐
peated or accepts a comma separated list of devices. This
overrides the devices file.
--devicesfile String
A file listing devices that LVM should use. The file must
exist in /etc/lvm/devices/ and is managed with the
lvmdevices(8) command. This overrides the lvm.conf(5) de‐
vices/devicesfile and devices/use_devicesfile settings.
--driverloaded y|n
If set to no, the command will not attempt to use device-
mapper. For testing and debugging.
--foreign
Report/display foreign VGs that would otherwise be skipped.
See lvmsystemid(7) for more information about foreign VGs.
-h|--help
Display help text.
-H|--history
Include historical LVs in the output. (This has no effect
unless LVs were removed while lvm.conf(5) metada‐
ta/record_lvs_history was enabled.
--ignorelockingfailure
Allows a command to continue with read-only metadata opera‐
tions after locking failures.
--journal String
Record information in the systemd journal. This informa‐
tion is in addition to information enabled by the lvm.conf
log/journal setting. command: record information about the
command. output: record the default command output. de‐
bug: record full command debugging.
--lockopt String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--logonly
Suppress command report and display only log report.
--longhelp
Display long help text.
--nameprefixes
Add an "LVM2_" prefix plus the field name to the output.
Useful with --noheadings to produce a list of field=value
pairs that can be used to set environment variables (for
example, in udev rules).
--noheadings
Suppress the headings line that is normally the first line
of output. Useful if grepping the output.
--nohints
Do not use the hints file to locate devices for PVs. A com‐
mand may read more devices to find PVs when hints are not
used. The command will still perform standard hint file in‐
validation where appropriate.
--nolocking
Disable locking.
--nosuffix
Suppress the suffix on output sizes. Use with --units (ex‐
cept h and H) if processing the output.
-o|--options String
Comma-separated, ordered list of fields to display in
columns. String arg syntax is: [+|-|#]Field1[,Field2 ...]
The prefix + will append the specified fields to the de‐
fault fields, - will remove the specified fields from the
default fields, and # will compact specified fields (remov‐
ing them when empty for all rows.) Use -o help to view the
list of all available fields. Use separate lists of fields
to add, remove or compact by repeating the -o option:
-o+field1,field2 -o-field3,field4 -o#field5. These lists
are evaluated from left to right. Use field name lv_all to
view all LV fields, vg_all all VG fields, pv_all all PV
fields, pvseg_all all PV segment fields, seg_all all LV
segment fields, and pvseg_all all PV segment columns. See
the lvm.conf(5) report section for more config options.
See lvmreport(7) for more information about reporting.
--profile String
An alias for --commandprofile or --metadataprofile, depend‐
ing on the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and
--verbose. Repeat once to also suppress any prompts with
answer 'no'.
--readonly
Run the command in a special read-only mode which will read
on-disk metadata without needing to take any locks. This
can be used to peek inside metadata used by a virtual ma‐
chine image while the virtual machine is running. No at‐
tempt will be made to communicate with the device-mapper
kernel driver, so this option is unable to report whether
or not LVs are actually in use.
--reportformat basic|json
Overrides current output format for reports which is de‐
fined globally by the report/output_format setting in
lvm.conf(5). basic is the original format with columns and
rows. If there is more than one report per command, each
report is prefixed with the report name for identification.
json produces report output in JSON format. See
lvmreport(7) for more information.
--rows
Output columns as rows.
--segments
Use default columns that emphasize segment information.
-S|--select String
Select objects for processing and reporting based on speci‐
fied criteria. The criteria syntax is described by --se‐
lect help and lvmreport(7). For reporting commands, one
row is displayed for each object matching the criteria.
See --options help for selectable object fields. Rows can
be displayed with an additional "selected" field (-o se‐
lected) showing 1 if the row matches the selection and 0
otherwise. For non-reporting commands which process LVM
entities, the selection is used to choose items to process.
--separator String
String to use to separate each column. Useful if grepping
the output.
--shared
Report/display shared VGs that would otherwise be skipped
when lvmlockd is not being used on the host. See
lvmlockd(8) for more information about shared VGs.
-O|--sort String
Comma-separated ordered list of columns to sort by. Re‐
places the default selection. Precede any column with - for
a reverse sort on that column.
-t|--test
Run in test mode. Commands will not update metadata. This
is implemented by disabling all metadata writing but never‐
theless returning success to the calling function. This may
lead to unusual error messages in multi-stage operations if
a tool relies on reading back metadata it believes has
changed but hasn't.
--unbuffered
Produce output immediately without sorting or aligning the
columns properly.
--units [Number]r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
All sizes are output in these units: human-(r)eadable with
'<' rounding indicator, (h)uman-readable, (b)ytes, (s)ec‐
tors, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes,
(p)etabytes, (e)xabytes. Capitalise to use multiples of
1000 (S.I.) instead of 1024. Custom units can be speci‐
fied, e.g. --units 3M.
--unquoted
When used with --nameprefixes, output values in the
field=value pairs are not quoted.
-v|--verbose ...
Set verbose level. Repeat from 1 to 4 times to increase the
detail of messages sent to stdout and stderr.
--version
Display version information.
-y|--yes
Do not prompt for confirmation interactively but always as‐
sume the answer yes. Use with extreme caution. (For auto‐
matic no, see -qq.)
VG Volume Group name. See lvm(8) for valid names.
LV Logical Volume name. See lvm(8) for valid names. An LV
positional arg generally includes the VG name and LV name,
e.g. VG/LV.
Tag Tag name. See lvm(8) for information about tag names and
using tags in place of a VG, LV or PV.
String See the option description for information about the string
content.
Size[UNIT]
Size is an input number that accepts an optional unit. In‐
put units are always treated as base two values, regardless
of capitalization, e.g. 'k' and 'K' both refer to 1024.
The default input unit is specified by letter, followed by
|UNIT. UNIT represents other possible input units: b|B is
bytes, s|S is sectors of 512 bytes, k|K is KiB, m|M is MiB,
g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This
should not be confused with the output control --units,
where capital letters mean multiple of 1000.)
See lvm(8) for information about environment variables used by
lvm. For example, LVM_VG_NAME can generally be substituted for a
required VG parameter.
The lv_attr bits are:
1 Volume type: (C)ache, (m)irrored, (M)irrored without initial
sync, (o)rigin, (O)rigin with merging snapshot, inte(g)rity,
(r)aid, (R)aid without initial sync, (s)napshot, merging
(S)napshot, (p)vmove, (v)irtual, mirror or raid (i)mage, mirror
or raid (I)mage out-of-sync, mirror (l)og device, under (c)on‐
version, thin (V)olume, (t)hin pool, (T)hin pool data, v(d)o
pool, v(D)o pool data, raid or pool m(e)tadata or pool metadata
spare.
2 Permissions: (w)riteable, (r)ead-only, (R)ead-only activation
of non-read-only volume
3 Allocation policy: (a)nywhere, (c)ontiguous, (i)nherited,
c(l)ing, (n)ormal This is capitalised if the volume is current‐
ly locked against allocation changes, for example during
pvmove(8).
4 fixed (m)inor
5 State: (a)ctive, (h)istorical, (s)uspended, (I)nvalid snapshot,
invalid (S)uspended snapshot, snapshot (m)erge failed, suspend‐
ed snapshot (M)erge failed, mapped (d)evice present without ta‐
bles, mapped device present with (i)nactive table, thin-pool
(c)heck needed, suspended thin-pool (C)heck needed, (X) unknown
6 device (o)pen, (X) unknown
7 Target type: (C)ache, (m)irror, (r)aid, (s)napshot, (t)hin,
(u)nknown, (v)irtual. This groups logical volumes related to
the same kernel target together. So, for example, mirror im‐
ages, mirror logs as well as mirrors themselves appear as (m)
if they use the original device-mapper mirror kernel driver;
whereas the raid equivalents using the md raid kernel driver
all appear as (r). Snapshots using the original device-mapper
driver appear as (s); whereas snapshots of thin volumes using
the new thin provisioning driver appear as (t).
8 Newly-allocated data blocks are overwritten with blocks of
(z)eroes before use.
9 Volume Health, where there are currently three groups of at‐
tributes identified:
Common ones for all Logical Volumes: (p)artial, (X) unknown.
(p)artial signifies that one or more of the Physical Volumes
this Logical Volume uses is missing from the system. (X) un‐
known signifies the status is unknown.
Related to RAID Logical Volumes: (r)efresh needed, (m)ismatches
exist, (w)ritemostly.
(r)efresh signifies that one or more of the Physical Volumes
this RAID Logical Volume uses had suffered a write error. The
write error could be due to a temporary failure of that Physi‐
cal Volume or an indication that it is failing. The device
should be refreshed or replaced. (m)ismatches signifies that
the RAID logical volume has portions of the array that are not
coherent. Inconsistencies are detected by initiating a "check"
on a RAID logical volume. (The scrubbing operations, "check"
and "repair", can be performed on a RAID logical volume via the
'lvchange' command.) (w)ritemostly signifies the devices in a
RAID 1 logical volume that have been marked write-mostly.
Re(s)haping signifies a RAID Logical Volume is either undergo‐
ing a stripe addition/removal, a stripe size or RAID algorithm
change. (R)emove after reshape signifies freed striped raid
images to be removed.
Related to Thin pool Logical Volumes: (F)ailed, out of (D)ata
space, (M)etadata read only.
(F)ailed is set if thin pool encounters serious failures and
hence no further I/O is permitted at all. The out of (D)ata
space is set if thin pool has run out of data space. (M)etadata
read only signifies that thin pool encounters certain types of
failures but it's still possible to do reads at least, but no
metadata changes are allowed.
Related to Thin Logical Volumes: (F)ailed.
(F)ailed is set when related thin pool enters Failed state and
no further I/O is permitted at all.
Related to writecache logical volumes: (E)rror.
(E)rror is set dm-writecache reports an error.
10 s(k)ip activation: this volume is flagged to be skipped during
activation.
